You explained it well enough . . . however some of us (well, 2 of us at 
least) do love wandering off topic.

Hopefully they fully intersect most of the time unless you are sleeping or actively astral traveling. (Not a good idea for the untrained)   but I would change the coloir scheme, substitute "light blue" for invisible (some people, children, cats *can* see them)  and it’s the same thing.  then when you die, all you just "delete" the first two objects (food body, energy body)  (ha!)
